Must Use Car Hacks

In today’s increasingly connected world, where technology plays a central role in our lives, it’s no surprise that cars have become highly advanced and integrated with digital systems. While this connectivity offers numerous benefits, it also exposes vehicles to potential security risks. Understanding the most common car hacks is crucial to safeguarding your vehicle and ensuring your personal safety.

Types of Car Hacks

Keyless Entry Hacks

Most used car hacks involve exploiting keyless entry systems, which have become increasingly popular in modern vehicles. Keyless entry systems use wireless communication between the key fob and the car to unlock and start the vehicle. However, hackers have found ways to compromise these systems.

Hackers often use relay attacks, where they intercept the signal between the key fob and the car, to gain unauthorized access. They can amplify the key fob’s signal from inside your home, for example, and trick the car into thinking the key fob is nearby.

To protect your vehicle from keyless entry hacks, consider the following tips:

  • Keep your key fob in a signal-blocking pouch or container when not in use.
  • Park your car in a garage or a location with limited wireless signal access.
  • Install additional security measures, such as a steering wheel lock or an immobilizer.

Remote Car Hacks

Remote car control systems, commonly found in modern cars, allow owners to remotely start, lock, or unlock their vehicles using mobile apps or key fob functions. However, these systems can also be vulnerable to hacking.

Hackers can exploit weak passwords or vulnerabilities in the mobile app or connected services to gain remote control of your vehicle. Once they gain access, they can manipulate various vehicle functions, including starting the engine or unlocking the doors.

To secure your car’s remote control functionality:

  • Use a strong and unique password for your remote control app.
  • Regularly update the mobile app and the vehicle’s software to fix any security vulnerabilities.
  • Disable unnecessary remote control features that you do not use frequently.

GPS Spoofing Attacks

Global Positioning System (GPS) systems are integral to modern vehicles, providing navigation, tracking, and other location-based services. However, hackers can spoof GPS signals, leading to potentially dangerous situations.

In GPS spoofing attacks, hackers manipulate GPS signals to deceive the vehicle’s navigation system. This can mislead the driver, potentially leading to wrong routes or destinations. In some cases, hackers can even tamper with location-based services, affecting the vehicle’s security measures.

To prevent GPS spoofing attacks:

  • Be cautious of sudden changes in navigation instructions and cross-reference with other sources, such as maps or road signs.
  • Install a reputable GPS anti-spoofing device or software that can detect and counter spoofing attempts.
  • Stay informed about potential GPS vulnerabilities and apply software updates provided by the vehicle manufacturer.

OBD-II Port Exploits

The On-Board Diagnostic II (OBD-II) port is a standard diagnostic port found in most modern vehicles. It allows mechanics and technicians to access and diagnose vehicle systems. However, this port can also be a gateway for
hackers if left unprotected.

Hackers can exploit vulnerabilities in the OBD-II port to gain unauthorized access to a vehicle’s internal systems. This can lead to remote control of the vehicle, disabling important safety features, or even tampering with the engine control unit (ECU).

To secure your vehicle’s OBD-II port:

  • Use an OBD-II port lock or cover to prevent unauthorized physical access.
  • Be cautious when connecting to unfamiliar or untrusted devices or diagnostic tools.
  • Consult with your vehicle manufacturer or a trusted mechanic about OBD-II port security measures.

Prevention and Countermeasures

Regular Software Updates

Keeping your car’s software up to date is crucial for protecting it against known vulnerabilities and exploits. Manufacturers often release software updates that address security issues and enhance the overall performance of the vehicle. Regularly check for software updates from your vehicle manufacturer and install them promptly.

Stronger Authentication Methods

Implementing stronger authentication methods can significantly enhance your vehicle’s security. Consider using biometric authentication, such as fingerprint or facial recognition, along with traditional methods like a PIN or password. Two-factor authentication, where you need to provide two forms of verification, adds an extra layer of protection against unauthorized access.

Secure Communication Protocols

Secure communication protocols play a vital role in preventing car hacks. The Controller Area Network with Flexible Data-Rate (CAN-FD) and Ethernet are examples of protocols that provide improved security. These protocols employ encryption and authentication mechanisms to safeguard data transmission within the vehicle’s network. When purchasing a new vehicle, inquire about the communication protocols used and opt for those with robust security features.

Physical Security Measures

While digital security measures are crucial, physical security is equally important. Installing additional physical security features can deter thieves and hackers from targeting your vehicle. Consider using steering wheel locks, wheel clamps, or car alarms to provide an extra layer of protection. Parking your vehicle in well-lit areas or secured garages also reduces the risk of unauthorized access.

Responding to a Car Hack

It’s essential to be aware of the signs that your vehicle may have been compromised. Some indicators include unexpected changes in behavior, such as difficulty starting the car, unusual dashboard warnings, or unexplained modifications to the vehicle’s settings. If you suspect a car hack, take the following steps:

  1. Disconnect from the Network: Turn off the vehicle’s Wi-Fi, Bluetooth, or any other connectivity options to sever the hacker’s access.
  2. Contact the Manufacturer: Reach out to your vehicle manufacturer’s customer support or security team to report the incident and seek guidance on how to proceed.
  3. Consult with Professionals: If necessary, consult with a trusted mechanic, automotive cybersecurity expert, or professional car hacking response team to assess the extent of the hack and restore your vehicle’s security.


As vehicles become more connected, the risk of car hacks continues to grow. By understanding the most common car hacks and implementing preventative measures, you can protect your vehicle’s security and your personal safety. Stay informed about the latest security updates, use stronger authentication methods, invest in physical security measures, and be vigilant for any signs of unauthorized access. With these precautions, you can enjoy the benefits of modern vehicle technology while minimizing the risk of car hacks.
